Looks like Princess Leia is happening.Carrie Fisher just spilled the beans.
Seriously, we knew this was what should happen, but so great to hear that it's what will happen. Just spectacular news.

From TheForce.net:

"One of our rebel readers, Curt, wrote in with the following:

"I was at Carrie Fishers booksigning in Cherry Hill, NJ on November 15, and the interview she did started with the question 'Are you really going to be in a new star wars movie?' and Carrie answered quietly 'Yes....I thought it was already common knowledge.' She did not elaborate, as she probably doesn't want to crow too loudly at this point in the project development. But this is the first confirmation from one of the main OT Cast. LFL has not said the cast would return yet."
